## Description

xgoose is an AI agent that lives in your browser. A small floating button opens a chat panel next to whatever website you're on. The agent reads the current page, runs JavaScript on your behalf, and follows site-aware "skills" - tiny programs that teach it how to use specific sites.

Highlights:
- Floating chat panel on any page: click the button, type what you want, and the agent gets to work.
- Reads and acts on the current tab: inspect the page, run JavaScript, and review console logs and network requests.
- Site-aware skills: install community skills to give the agent step-by-step know-how for specific sites.
- Bring your own key: use OpenAI, Anthropic, Gemini, or OpenRouter - or the free built-in gateway.
- Open source: the Chrome, Firefox, and Safari hosts all share the same agent core.

You stay in control: the agent only acts on the current tab when you ask it to. xgoose is experimental software.
